WATERBORNE COATINGS FOR INTERIORS

1

An environment-friendly attitude is increasingly spreading, aiming at safeguarding the operators’ and the end-users’ health. For this reason, furniture is more and more being coated with products with the least emission of solvents, both during the painting stage and in the final slow stage of the drying, which usually occurs at home and liberates unpleasant odours. As furniture manufacturers use chipboard bases and MDF with low formaldehyde contents, painters will have to use products with minimum contents of harmful substances, so as to protect the environment.

Sayerlack is committed to this research. Hydroplus is the brand of the best waterborne coatings for interiors.

The appearance is critical in the coating of furniture and its accessories. The Hydroplus waterborne products result in finishes that cannot be differentiated from those obtained with solvent-based products, ensuring a mechanical and chemical resistance level comparable to that of polyurethane two-pack topcoats.However, these results can only be reached by following some instructions that help the process obtain the best performance of the coatings.The naturally variable nature of wood means that it must be carefully prepared prior to coating. The use of top-quality materials will also give the best results.

Excellent chemical resistance.Non-yellowing acrylic systems.

One-pack waterborne coatings have no pot-life problems like the conventional polyurethane solvent-based products.They are simple and ready to use as the product can be recovered and used again provided it is poured in its original can and carefully sealed, thus avoiding a prolonged contact with air, or immediately reused after having recovered its viscosity by diluting with water.

If you need the top performance given by the addition of an isocyanate curing agent (kitchens, furniture for bars and discos, table surfaces..), you can use AH 1545 or AH 1550. This product chemically reacts as it happens with polyurethane products; however, thanks to its special composition, it is stable and mixable with waterborne products, thereby ensuring a pot-life of several hours, after which the residue material cannot be used anymore.

GENERAL INSTRUCTIONS

Veneer. Special care must be taken during the veneer gluing step. To have good bonding in critical points, such as sharp edges or imperfect joints, it is necessary to use ureic or class B3 or higher glues, and these must be spread and pressed evenly on the panel.

Sanding. At the end of the preliminary steps and after the support settling period, the item is ready for sanding. This is carried out by sanding the bare wood with increasingly finer grain abrasive papers (such as 150 and 180), in order to limit the raising of wooden fibres caused by the water contained in the products.The more accurate the support preparation, the better the performance of the coating product.

Packaging. Due to the quite high chemical resistance of waterborne topcoats for interiors, the packaging used by clients usually gives no problems; however, the best material for packaging is high-density foamed polyethylene, while PVC or pluriball are not recommended.

Equipment cleaning. After the equipment has been used, this must be washed with water to prevent dry residues. A deeper cleaning is carried out periodically using the special detergent for waterborne products XA 4060, leaving the equipment to soak for a few hours.The same equipment should not be used for water and solvent-based coating systems.

Application systems. Hydroplus coatings can be applied by spray (conventional, airless, airmix, electrostatic), provided that the equipment is suitable for water contact. Specific equipment for water-based coatings is required for electrostatic application. Below are some general indications for spray application.

The use of a binder may be required to improve some aspects of stains: quick drying, pore marking, evenness; or for specific use, dipping, roller application or antique stains.

CroSS-linker

XA 4080The use of a cross-linker is not necessary, however, it is useful in particular:

in the basecoats- To improve their sandability (with Scotch-Brite or un-spaced abrasive papers).- To reduce thermo-plasticity and improve over-coating with solvent-based products.

in the topcoats- To improve chemical and mechanical resistance.- To accelerate stackability.

XA 4095Is specific for painting systems on glass with waterborne products.

BinDer

BleedingMany stains on the market and many substances present in several wood species are soluble in water. For this reason, they are responsible for an effect called “bleeding”, which occurs when these substances dissolve into the coating. The bleeding effect sometimes is requested in order to improve the deepness and brightness of the stain, but more frequently it is a collateral effect with several negative consequences not completely under control when not suitable stains are used, like: remarked sagging, sweating of colour from the paint, if wetted, or, in some species of wood, greenish coloration or black spots from the pore. Therefore, it is recommended to use only stains and binders approved with waterborne products. All the stains and binders displayed in this brochure are approved for use with waterborne products.

Waterborne Products on GlassAlmost all waterborne coatings with the addition of XA 4095 show good adhesion on glass. Anyway, the best results are obtained with AV 19**/XX. This product is specific for application on glass, helping to obtain more homogeneous application and better adhesion.
